Many techniques have been proposed in the recent literature that look to deliver improved net-work spectral efficiency by managing interference. These include Multi-antenna techniques, antenna polarimetric techniques, DSA based approaches, interference alignment techniques, and multiuser detection (MUD) techniques. To date, however, these techniques working in isolation have fallen short of achieving close to the theoretical bounds suggested. To approach this limit, a unified strategy is needed that combines a multiplicity of such techniques and optimally combines their impact. The aim of this effort is to bring together the aforementioned techniques in a unified manner so as to significantly improve spectral efficiency of a wireless network. Our objective is to deliver a 50x improvement in the network spectral efficiency (measured as bits/s/Hz/sqr-km) relative to a baseline military system utilizing a 10 Watt QPSk rate ½ PHY with a 17 slot TDMA MAC.
